LONDON—The dollar held close to a six-month peak as jitters over China and global growth weighed on risk appetite, while the yen strengthened as Japan’s top currency diplomat sent a warning about the currency after it earlier dropped to a 10-month low.
The yen strengthened by as much as 0.4 percent to 147.02 per U.S. dollar after Japan’s top currency diplomat, Masato Kanda, said they won’t rule out options if speculative moves persist, the strongest warning since mid-August.
